SPECIFICATION forming part of Letters Patent No. 754,649, dated March15, 1904.-

Applieation filed l'uly 15, 1902. Serial No. 115,642. (No model.)

To aZZ whom it may concerm Be it known that I, ERNST GEssNER, a subjectof the Emperor of Germany, and a resident of the city of Aue, Kingdom ofSaxony, Empire of Germany, have invented a new and useful Improvement inCloth-Holding Devices for Textile Machinery.

Heretofore in machines for tentering and drying cloth the mechanism forholding the cloth has generally consisted of two chains each of whichwas armed with upright pins upon which the selvage edges of the clothwere impaled. At the entrance to the machine the chains werecomparatively near together, so that the selvage edges could beconveniently placed upon, the pins by hand. From this entrance-point thechains diverged from each other, so as to stretch the cloth to therequisite width for the drying or tenter- 2O ing operation. Although theattendant could by hand place the edges of the cloth upon the pins, hehadnot suflicient time to impale the cloth upon the pins, and for thispurpose pressure-wheels were located along the path of.

5 the chains to produce the impaling before the diverging of the chainscommenced to stretch the cloth. The placing and impaling of the clothupon the pins in this manner was open to serious difiiculties, as wellasthe holding of 3 the clothin this'way during the drying or tenteringoperation.

I have discovered that the impaling of the cloth upon the pins may beautomatically accomplished by the pull of the cloth itself, and

one part of my inventionconsists of a device for utilizing thisdiscovery. This device sat isfactorily overcomes the objectionsattendant upon the old method and also satisfactorily holds the clothduring the drying or tenter- 4 ing operation and also is of such acharacter as to permit of the ready disimpalement of the cloth from thepins as the'chains converge toward each other at the exit of the clothfrom the machine. Other features of my invention will be pointed out inthe claims.

In the accompanying drawings, Figure 1 is a cross-section of sufficientof the machine to represent a simple form of my invention. Fig. 2 is aplan of the same. Figs. 3, 5, and

5 7 are cross-sections of sufficient of the machine to represent each amodified and additional form of my invention. Figs. 4:, 6, and

8 are corresponding plan views of the same. Figs. 9 and 10 representamodification. Figs.

11 and 12 are diagrammatic views in elevation and plan of the machine inwhich my invention is employed.

My device is shown in its simplest form in Figsl and 2, which form willbe first described. a I

a a. a a are links of the chain of a drying or tentering machine, everyalternate link of which is provided with an opening A to receive thesprockets of the wheels by which the chain is supported and driven. Thelinks 5 of this chain have tongues j and ,clevis forming pivots whichare so arranged that the connecting-pins I I I are alternately at rightangles with each other. The chain is supported and guided from below byguide- 7 bar D and is guided in the desired vertical plane by the tongueOZ extending downward from the guide-bar D into a groove formed betweenthe outeredge of each, alternate link a a and a flange C, fixed to suchouter edge.

The mechanism which I will next describe is duplicated on each of thealternate links a (f, &c., of the chain, a description of one answeringfor all.

B is a flange extending horizontally from and fixed to the inner side ofthe link a and havinga foot-piece b to rest upon the guidebar D; I

B is a cloth-plate resting and secured in any suitable manner upon theflange B at such 5 an elevation that its upper surface is insubstantially the same plane as the axes of the pins I and 1 Thiscloth-plate B has diverging sides, so that its greatest length is nearlyequal to the distance between the centers of the pins I I The efiect isthat the series of cloth-plates B B B form a nearlycont'inuouscloth-bearing surface and enable the se-. ries of pins upon which thecloth is impaled to be substantially continuous and equidistant fromeach other.

E is an overhanging arm fixed to the inner edge of the link a andextending inwardly toward the opposite chain farther than thecloth-plate B. The extremity of this over- I00 hanging arm is providedwith a cross-piece E, in which is journaled the pin E Fixed to the endsof this pin are the downwardly and outwardly inclined arms ff, whichcarry at their extremities the cross-bar F, to which is secured thepin-plate Gr, carrying the series of pins G. The series of pins carriedby each link a is sufiiciently extended to form a substantiallycontinuous series with the adjacent series of pins supported on otherlinks.

H H are two fingers or feelers fixed to the bar F, which are capable ofoscillating arou nd the center E through the slots 5 12 in thecloth-plate.

f is a finger fixed by a yoke f to the arms ff and extending upwardlyabove the overhanging arm. e is a stop on the overhanging arm, wherebythe motion of the finger f is limited.

6 b, &c., are a series of slots or notches in the edge of thecloth-plate through which the series of pins G may oscillate around thecenter of E The operation is as follows: At the entrance to the machine,where the chains are comparatively near together, the selvage edge ofthe cloth goes onto the cloth-plate in the position shown at J, Fig. 1.The presence of the cloth in this position supports the feeler H, andconsequently the series of pins G, in the position shown in full linesin Fig. 1. As the cloth and chain advance from the entrance toward thedrying or tentering chamber the recession of the chains from each othercauses the edges of the cloth to slip toward the inner edge of thecloth-plate until the cloth edge slips from under the feelers H andpermits the feelers to drop into the slots 6 b and permits the scries ofpins G to rest upon the surface of the cloth. In this position the edgeof the cloth is still supported from below by the clothplate B and theseries of pins rests on top of it. As now the recession of the chainsfrom each other is continued the opposition of the cloth to beingstretched will pull the edge of the cloth still farther inward over thatportion of the cloth-plate containing the series of slots 6. Thismovement, however, carries with it the series of pins resting upon thecloth, which, moving around the center of E pass down through the slots'6, and therefore are compelled by the pull of the cloth itself tothoroughly impale the cloth. As the inward movement of the edge of thecloth proceeds still farther, owing to the further divergence of thechains, the edge of the cloth will fall off of the inner edge of thecloth-plate by the time that the series of pins reaches the positionshown in dotted lines in Fig. 1, so that by the time the chains havereached their greatest distance apart and begin to run parallel witheach other the edge of the cloth will be held exclusively upon theseries of pins G. The stop 0 holds the series of pins at each edge ofthe cloth in the outwardly inclined or diverging position, (shown indotted lines in Fig. 1,) so that as the cloth passes through the dryingor tentering chamber the cloth tends to hold itself securely upon theseries of pins by its own tendency to shrink or oppose the stretching.As soon as the cloth has passed out of the drying or tentering chamberand the chains begin to converge toward each other the slack therebyproduced crosswise of the cloth will enable it to be readily stripped bythe pull of any suitable draft-roll from the series of pins at eachedge. Thereafter any suitable device engaging the arm f' returns theparts to the position shown in full lines of Fig. 1 and retains themthere, ready to receive a new portion of the cloth at the entrance ofthe machine. During all of this operation the cloth is protected frombeing spotted by oil or grease by the location of the guiding-tongue dand its engaging groove exclusively on the opposite side of the chainfrom the. cloth. This location of said guide also enables thewearing-surface to be increased.

In the modification shown in Figs. 3 and 4 the parts already referred toare, with the exceptions below noted, substantially as alreadydescribed; but in addition thereto means is provided for straighteningout the list-curl of the cloth, if such occur. This consists of anuncurling-plate K, which is pivotally mounted upon the pin E. It restsupon a stop k fixed to the overhanging arm, and is therefore capable ofbeing raised above but not lowered below the position shown in Fig. 3,where the distance between its lower edge and the upper face of thecloth-plate is just sufficient to accommodate the thickness of thecloth. This stop can be made adjustable, as byaset-screw, if desired. Asthe edge of the cloth is, as before described, drawn inwardly over theclothplate any curled list, such as that shown in Fig. 3,will bestraightened out by the plate K pre-' paratory to being impaled by theseries of pins, The plate K is preferably held in the position shown inFig. 3, inclined to the surface of the cloth. In Fig. 3 the functionwhich in Fig. 1 was performed by the stop a is performed by theengagement between the projection f on the arm f with the projection onthe uncurling-plate K, as shown by dotted lines in Fig. 3. To insurestraightening of curled lists if they happen to turn under, I form arecess or groove L, the edge thereof which engages the curl in the clothlying beneath the corresponding edge of the uncurling-plate K,

IIO

the edges of both the uncurling-plate K and might be used; but a clearopen space provides room for the roll to drop down in better position tobe uncurled than if there were ribs to the chain.

hold portions thereof at the level of the cloth plate. I

The construction shown in Figs. 5 and 6 is substantially like that shownin Figs. '3 and i, the principal difference being that theuncurling-plate K is hinged on special pivots N,

' carried by the arm E nearer to the chain than the pivot E Slots 7c inthe plate K accommodate the feelers H. The plate K is raised byengagement with the feelers H. In this construction the arm f isconnected with the arms f and f.

In Figs. 7 and 8 the construction shown differs from that shown in Figs.5 and 6 in having the smoothing or uncurling plate K pro- Vided witharms K pivoted at N entirely outside of the cloth or between the clothand the chain. The ends of the feelers H extend be neath the plate K andlift it when the pinplate is swung inward and upward or toward InFigs.7, 8, 9, and the flange B of the other figures is replaced by arms M,which are shown as directly beneath the arms E, although this is not anessential position.

In Figs. 9 and 10 the feeler-arm H is an extension of the arm f, and thefeeler H is made I I of such shape that it acts as the smoothing or thechain is led to the point of attachment, are

on separate studs or shafts set at an angle to each other, so that theplanes of the wheels g g converge and'cause the chains to converge asthey rise from below to the point of attachment. h h are the trackways,the general trends of which diverge to the dryingmachine proper andthence extend parallel back and forth through the machine. From thewheels 2', at which the cloth is detached, each chain extends loosely,as shown, to its entering wheel.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. In a cloth-holding device for textilemachinery, in combination, a cloth-support, a series of pins and meanswhereby said pins are forced to impale said cloth by the pull of thecloth on said pins.
